DT850L 디지털 멀티미터

주요 측정 항목은 전압, 전류, 저항입니다. 교류와 직류의 지원 범위는 모델별 사양을 확인하세요.

가전 점검이나 전자 제작 등 많은 작업에 읽기 쉬운 기본형을 사용할 수 있습니다. 상용 전원 측정 시에는 측정 지점에 맞는 측정 카테고리도 확인하세요.

직류 전압 정확도는 모델에 따라 일반적으로 0.5~1 %입니다. 측정 범위별 상세 정확도는 모델 사양표에서 확인하세요.

For a first order, stock the DT830 or A830L as the entry price point and the DT838 or DM101 as the step-up tier. That gives you two price bands without tying up container space in slow SKUs, and you can add DT832, DT858L or XT802 later based on sell-through. If you are not sure which band sells in your market, order both in roughly equal quantities and reorder from the data. Compare the full functions on each model's specifications table before you fix the mix.

Most distributors run two tiers for this line: the DT830, DT830L and A830L for hardware and home channels, and the DT838, DT850L or DT858L for trade and auto customers who pay up for the step-up model. You can keep a single SKU to simplify stock, but splitting the order lets you match price bands to each channel. Tell us your expected split by customer type and we will quote per-model pricing for the full order.

Yes, we are the factory in Wenzhou, so we can print your brand on the meter face, the dial and the box for the basic DMM line, including DT830, DT832, DT838, DM101 and the rest of the range. For retail we offer printed color boxes with a fitted insert; for cost-sensitive programs we ship bulk packs with a plain carton and your label applied. Send us the models and packaging you want and we will confirm print minimums and artwork lead time for each model.

Return the defective meters with your order number and we will repair or replace them at our Wenzhou factory, and we check the same production lot so you can keep the remaining stock on the shelf with confidence. For wholesale orders we process claims by lot and can credit the replacement value against your next order to save on return freight. The process covers the whole basic DMM line, from the DT830L to the XT803.

Most of our multimeters have a capacitance range, so you do not need a separate LCR meter for the everyday job of finding a failed capacitor. The XT802 covers 4 nF to 40 mF at ±10.8%, and the DT6222 covers 4 nF to 4 mF at ±3.5%. A bench LCR meter is still the better instrument if you need leakage, ESR or dissipation factor, because a multimeter only reports capacitance.

The printed figure is a nominal value carrying its own tolerance, commonly ±5% for film and ±20% for electrolytics, so a small difference is normal and not a meter fault. A reading far outside that band usually means the capacitor has drifted or dried out rather than that the instrument is wrong. Check the meter against a capacitor of known value before you act on a surprising result.

Discharge it, then lift at least one leg before measuring. In circuit, everything connected in parallel with the capacitor adds to the reading, and any discharge path makes the value drift while you watch it. With one leg lifted the reading settles within a second or two, and that is the number worth recording.

Most repair work sits between 1 nF and 1000 µF: film and ceramic parts in the low nanofarad region, electrolytics in the microfarad region. The DT6222 covers 4 nF to 4 mF on a 4000-count display, so small values still have useful resolution. The XT802 spans 4 nF to 40 mF if your work reaches the large electrolytics as well.
